These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fan-Preferred Couple: A lot of Fred fans were disappointed Fred ended up with Judy in the end and not Bertha. Incidentally there were four endings written for the movie, one of which being Fred and Bertha becoming a couple.
Film critic Mark Kermode claimed that Fred's shrieks were so unbearable that he had to stuff things in his ears in order to continue watching the film.
Nightmare Fuel: In recent episodes, Fred is harassed by an extremely creepy man named Claudio. In Fred Gets Kidnapped by Claudio, he is introduced by randomly breaking into Fred's house, kidnapping him, and locking him in a pet carrier, and then when Fred's mother catches Claudio, she allows him to stay because he will pay her, despite the fact that he just kidnapped and caged her son. In the next episode, Fred is Left Alone with Claudio, Fred's mother LEAVES FRED ALONE WITH HIM and Claudio continues to do more creepy and outright messed-up things to harass Fred. Brr..
One-Scene Wonder: John Cena's appearance in his film was pretty funny, and to most the only funny bit in the film.
Surprisingly Improved Sequel: The first two Fred movies were pretty forgettable, the third though is actually considered quite good by the fanbase. Helped that it got a few well known names attached to it.
